powering the "fridge"

Thus far, I've been restricting my use of perishable foods in the van, because I'm hesitant to power my DC-powered cooler (the replacement for the van's stock fridge that's been removed) while I'm not driving, and I don't drive enough in a typical day to run the cooler enough to keep it cold. But I have a solution now. I've ordered a portable battery "powerpak" that can be charged via AC electricity, DC, or even solar power. Once charged, it can power both AC and DC appliances... plus it has a built-in air compressor and jumper cables-- good "peace of mind" features for use in the van. Now I can look forward to stocking my "fridge!"

I did consider just getting a deep cycle house battery to stash in the typical place under the driver seat, but I like the portability of the powerpak, its versatility (3 options for charging), and its added capacity for filling my tires and jump starting my engine. Besides, I can always add a house battery later, and attach it to the powerpak via the jumper cables, to join their capacities. But I'd rather get a solar panel first...
